4. Manage the Aftermath: After the feast is finished, there are two inevitables: leftovers and cleaning. When storing what's left, eschew Saran wrap and aluminum foil, which get used a time or two before heading to the landfill. Opt instead for reusable containers. Consider, too, asking guests to bring their own containers so they can take home leftovers -- that way, you won't get caught trashing days-old turkey (or Tofurky) in early December.
